Just did the last of the week 3 runs. Each one has gotten harder. Unexpected. I’m not sure if it has to do with starting the Power 90 thing after the first run, or a build-up of fatigue on my knees and shins, or a diet thing (I’ve been eating 1000-1500 calories a day, which is way lower than I should be. And probably not enough fat, too. Also, I don’t eat in the mornings nearly as much as I should, so it could be a fuel problem). But my legs felt like lead today. Pace was down, distance overall (of course) was similarly down. Cramping a bit more than usual, too.
I’m not sure if I should do a week 3 run 4, or move on to week 4.
